Head-Neck-Hand

Wool or Fleece Hat - If you're bald like me this is a MUST! I miss the natural insulation on top of my head so I always have warm gear for my head. Even if you still have your hair, a warm hat is still a good idea.

Glove Liners or Mittens - For Philmont in August these were a maybe. When we went to Rocky Mountain High Adventure base and summited a 14'er (Mount Shavano) I wished I had brought gloves.
